To all whom it may concern:

Be it known that I, llf'ALTnn F. PHELPS, a citizen ot the United States residing at Dayton, in the county of Montgomery and'State of Ohio, have invented certain new and uselul Improvements in Supporting- Bases for Electric Fans7 and I do declare the following to be a i'ull, clear, and exact description ot' the invention, such as will enable others skilled in the :art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters and figures of reference marked thereon, which iorm a part oi this specification.

This invention relates to new and useful improvements in electric fans, and has specic reference to improvements in the motor and fan-supporting element.

The object of the invention is to provide an interchangeable or .convertible base or supporting element upon which the motor and tan with the adjuncts are supported, and whereby said base or supporting element is rendered capable of being converted from an ordinary desk or table stand to a wall bracket and vice versa, so that a single base or supporting element for the motor and ian may become a fixture or not as the needs of the case require. Y

Preceding a detailed description or' my invention, reference is made to the accompanying drawings, orn which- Figure 1, is a side elevation or' the base or supporting element with an and motor thereon, and the supporting base converted into a wall bracket. Fig. 2, is a similar view showing the same utilized as a desk or table stand. Fig. 3, is a rear elevation oi' Fig. 2. Fig. 4, is an enlarged sectional View on the line i-i oi Fig. 3. Fig. 5, is an enlarged detail view oi' the upper end ot the convertible supporting base.

In a detail description oi the invention, similar reierenee characters indicate corresponding parts.

The base or main supporting element 1 is suitably broadened or increased in area at its base, andthe same may be utilized as an ordinary stand tor a desk or table ian as in Fig. 2, or it may serve the purpose of a wall bracket or support foi-'the fan as shown in Fig. 1; in the former case, it needv not be fastened or united to the desk or table owing to its increased base area, but when utilized as a wall bracket or support it is obviously necessary that a rigid connection with the wall shall be made, this may be done in any suitable manner. In order to thus utilize the supporting element for the purposes of a stand or bracket, l'. provide therein two distinct apertures 2 and 3, the former being in a line with the major axis ot' the base, and the other aperture, towit-3, being at right angles to the aperture 2 and communicating therewith by entering the neck ot the base on the side thereoi'. Extending from the opening 2 to the opening 3 is a slot 4 which enables the conducting wires not shown) from the source of electrical supply ior the motor, to pass with the motor l'rom one position to the other in converting the base from a stand to a bracket and vice versa. The conducting wires enter the base through a suitable opening and pass through the opening 2 in the neck of the base and thence through the usual opening provided in the yoke 5, returning in the same manner.

There is no novelty in the marmer of connecting the supply wires with the motor circuit, therefore, it has not been deemed necessary to illustrate the same. Stem G oi the yoke 5 is tubular in order that conducting wires may pass therethrough to connect with the motor circuit. The said stem 6 enters the orifice 2 in the end oi the neck of the base and has an enlarged annular abutting portion 6 of an ornamental character which engages the upper end of the base or the neck and thus imparts to the joint thus formed an ornamental appearance.

When the base is utilized as a desk stand as in Fig. 2, the yoke stem 6 enters the axial opening 2 in the neck and is secured rigidly by one or more binding screws 7 which enter the neck of the base; in this adaptation of the base or supporting element 1 the side aperture 3 is closed by an ornamental plate 8.

In utilizing the supporting element for a bracket or wall support as in Fig. l, the yoke stem 6 is inserted in the side opening 3, the plate S being removed therefrom and placed over the end aperture 2 to close the same. ln thus changing the position of the motor yoke 5, the slot 4 permits thewires leading to the motor circuit to pass with the yoke from one position to the other. When projected into the side opening 3 in the base the yoke stem 6 is made secure by the requisite number oi binding screws 7, one of which enters the wall 9 of the neck and penetrates into the side opening 3. It will be readily seen that whether the yoke -be supported in the axial opening or the side opening in the neck ol' the base, it may be deflected or adjusted to any desirable position and therewith the ian and the motor to change the currents ot' air created by the revolving ian blades 10, and in such position said yoke may be secured by the binding screws 7.

When the axial opening 2 is utilized as in the case of a desk ian, the motor and tan may be adjusted or moved to any position within the limits of the slot 14 in the stem G by loosening the binding screw and swinging the motor yoke around to the desired position limited by the slot 14 and the screw 15, and then tightening said screw 7 The iorks of the yoke 5 have apertures in their extreme ends to receive binding screws 11 which engage apertured lugs 12 on the opposite sides of the spherical motor casing 13. The angle or position of the motor and ian may be adjusted by means ol the binding screws 7. It will thus be seen that different adjustments may be given the fan.

Having described my invention7 I claim:

l. ln an electric tan, a supporting base convertible into a stand or a wall bracket, said base having openings respectively in a line with the major axis thereof and at right angles to said axis, said openings so arranged at right angles communicating with each other by a slot, and a fan and motor-supporting yoke having a stem portion adapted to enter either of the openings in the base, and means for securing said yoke in either position.

2. In an electric fan, a supporting base convertible into a desk stand or wall bracket, said base having in its neck portion two apertures extending at right angles, the inner terminal oi' one of said openings communicating with a side ot the other ot' said openings, and a slot extending' through a portion ol the neck of said base and forming a passage from one opening to the other, a plate adapted to close either of said apertures when one is not utilized, a yoke supporting the fan and motor, said yoke having a stem adapted to enter either aperture in the neck of the hase and to be supported therein, and means for securing said yoke in such positions.

3. ln a convertible stand for an electric motor fan, a supporting base provided with openings in line with the major axis thereof, and at an angle to said axle, said openings communicating with each other by means of a slot extending through the side of said base, anda motorsupporting part having a stem portion adapted to be secured in either ot the openings in said base.

4. A supporting base for electric motor fans having at its small end two hollow extensions lying at right angles to each other and communicating by means of a slot extending therethrough, in combination with a motor-supporting yoke which is adapted t0 be supported on one or the other of said hollow extensions to vary the position of the motor fan, the slot forming the communication between said hol- .low extensions affording means for permitting the conduct- C.
